Thanks for your reply IRstuff. Can you give me the link to those sites you mentioned? As for 3D printing, that's indeed an interesting idea. Do you thing the material is strong enough though? (I'm not familiar with the material used) Will the pins withstand the stress of the strokes in the...

Hi everyone, I was wondering if anyone knows how music box drums are made. From what I've seen in a video, one type is basically a metal sheet rolled into a hollow cylinder. Small holes are drilled on the cylinder. Then, wire is inserted into each hole and is trimmed. The cylinder is then...

Hi everyone! I've been tasked to select/design an optimal condition monitoring system for our factory's centrifugal ductile iron pipe casting machine(s). Here's some info on the machines: - There's 3 of them, machines #1 and #2 are for pipe sizes from DN100 to DN350 and #3 is for DN400 to...

Thanks a lot people.

Hi everyone. Are there any standards or books about pressure gauge Bourdon tubes and movements which explains criteria such as general design, dimensions, material, manufacturing procedure, heat treatments, etc.? If not, can anyone answer the following questions for me? * Is the mechanism and...

hi dear katharine i really appreciate your consideration. but i have seen some data sheets of customers that mentioned that they need level transmitter displacer type for their interface application. they have even mentioned about their fluids . your tip that said thickness of upper fluid should...

as i read articles and data sheet of masoneilan level transmitter displacer type i did understand that for interface application the displacer must always immersed in fluid with lower density. i need to know how can i sure that this will happened . and if it doesn't happen what would be wrong...

Thanks a lot.

Thanks. That was really good.

Hi everyone, I'm looking for top instrument calibration brands (temperature, pressure, etc.). More specifically, I'm looking for cheaper alternatives to Fluke! Your suggestions will be highly appreciated. Thanks.

Hi everyone. I was wondering if anyone could help me with the following questions regarding pad type tube skin TCs: - If I'm not mistaken, the material of pad and MI cable sheath for tube skin thermocouples must be the same, otherwise the couple might introduce an unwanted voltage in the...

Thanks for the info. I do believe our customer also meant 2-1/16. My problem is that the table for blind flanges in API 6A (Table 46 in 19th edition) starts from size 5-1/8 for the pressure rating I require. For unlisted sizes, the table refers me to another table (44, which is for blind and...

Hi everyone. I'm a bit confused about an item our customer has required from us in a project. The item is a blind 2 inch API flange of 10K rating (I assume it should be a 6BX flange, right?). The problem is that the nominal size of blind 6BX flanges in API 6A standard starts from 5...

Thanks a lot, but I'm actually looking for info on instruments such as float/displacer switches/gauges and torque tube transmitters.

Thanks a lot.
